Answer:

Step-by-step explanation:

the radius is half the diameter:

7/2 : 2 = 7/2 x 1/2 = 7/4 cm

the circumference is:

diameter x π = 7/2π cm

the approximate circumference is

7/2 x 3,14 = 10,99 cm

You pull out the plug from the bathtub. After 40 seconds, there are 13 gallons of water left in the tub. One minute after you pu

SCORPION-xisa [38]

Answer:

g = -3/20s + 19

Step-by-step explanation:

Let's assume this is a function

<u>The points are</u>

(40, 13) and (60, 10)

<u>Since it is linear relation, we'll get the slope intercept form</u>

g = ms + b, where g- number of gallons, s- time in seconds, b- y intercept

<u>Using the points, let's calculate the formula</u>

m = (10 - 13)/(60 - 40) = -3/20
10 = -3/20*60 + b
10 = - 9 + b
b = 19

<u>So the formula is:</u>

g = -3/20s + 19

Asha bought 60 fruit baskets.

AleksAgata [21]

Total number of fruits is 60 which is:

75% + 25% = 100%

hence 45 + 15 = 60

<h3>Breakdown of the model</h3>

Total number of fruits is 60

25% represents a quarter of the fruits which contains 12 pieces of fruits in each basket

number of fruit basket in 25% is calculated below:

$\frac{25}{100} * 60=15$

the 25% of the fruit basket is 15 fruit baskets

75% represents three quarters of the fruits which contains 15 pieces of fruits in each basket.

number of fruit basket in 75% is calculated below:

$\frac{75}{100} * 60=45$

the 75% of the fruit basket is 45 fruit baskets.

Total number of fruits is 60 which is:

75% + 25% = 100%

hence 45 + 15 = 60

6. What are the zeroes for the<br>function<br>f(x) = 2x3 + 12x – 10x2?<br>

agasfer [191]

Answer:

Step-by-step explanation:

f(x) = 2x^3 + 12x – 10x^2 can and should be rewritten in descending powers of x:

f(x) = 2x^3 – 10x^2 + 12x

This, in turn, can be factored into f(x) = x·(x² - 10x + 12).

Setting this last result = to 0 results in f(x) = x·(x² - 10x + 12).

Thus, x = 0 is one root. Two more roots come from x² - 10x + 12 = 0.

Let's "complete the square" to solve this equation.

Rewrite x² - 10x + 12 = 0 as x² - 10x + 12 = 0.

a) Identify the coefficient of the x term. It is -10.

b) take half of this result: -5

c) square this last result: (-5)² = 25.

d) Add this 25 to both sides of x² - 10x + 12 = 0:

x² - 10x + 25 + 12 = 0 + 25

e) rewrite x² - 10x + 25 as the square of a binomial:

(x - 5)² = 13

f) taking the sqrt of both sides: x - 5 = ±√13

g) write out the zeros: x = 5 + √13 and x = 5 - √13.

The three roots are x = 0, x = 5 + √13 and x = 5 - √13.
